The borough contains a lead-contaminated parcel of land commonly known as the Marjol Battery site. Now owned by Gould Electronics, the empty land was a former battery processing facility closed in April 1982. Since the late 1980s, the federal United States Environmental Protection Agency and the state DEP have worked to clean up contamination in adjacent areas, but a final remedy for the site itself has remained on hold in recent years, as local officials and citizens fight with the government agencies and Gould over the best solution. In the meantime, the landowner has maintained a policy of basic containment and monitoring.

Throop's most popular summertime event is its annual Cow Flop organized by the Throop Booster Club. It has been a tradition in Throop since the late 1980s. The Flop serves as a fundraiser for the club and usually raises about $10,000 annually to benefit youth baseball and softball programs in the borough. The Flop, formerly held on a Sunday in late June, is now a two-day (since 2007) event that features a parade, fireworks, music, food, and other entertainment. The event requires more than 100 volunteers, mostly members of the Booster Club and parents of throop athletes, to produce. The main event of the Cow Flop is the raffle involving 2,000 squares and a cow's pick as to where she will relieve herself. Raffle tickets are $10 and the winner of the annual Flop raffle wins $5,000.[2]
